Security door based on face recognition

Abstract

The invention relates to a security door based on face recognition, which comprises a base, a top plate, a speaker, a processor, a shielding mechanism, a recognition mechanism and two side plates. Theshielding mechanism comprises a lifting assembly, a lifting plate and a baffle; the end of the lifting plate away from the baffle is provided with a notch; a telescopic assembly is provided in the notch; the recognition mechanism comprises a recognizer and a boom; the recognizer is provided with a display and a shooting assembly; the shooting assembly comprises a drive unit, a carousel and threecameras; the drive unit comprises a translation unit, a rack, a gear and a concentric shaft. The security door based on face recognition can block back head of visitors by the baffle of the shieldingmechanism to prevent images of faces captured by the cameras from being too complicated, and avoid affecting judgment of a device. Moreover, the recognition mechanism uses the cameras with different focal lengths to shoot from three different distance positions, separately. A distortion of the face is reduced by three sets of images; recognition accuracy is ensured; and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the field of face recognition equipment, in particular to a security gate based on face recognition. Background technique [0002] Face recognition is a biometric technology for identification based on human facial feature information. A series of related technologies that use a video camera or camera to collect images or video streams containing human faces, automatically detect and track human faces in the images, and then perform facial recognition on the detected faces, usually also called portrait recognition and facial recognition. [0003] Because face recognition has the function of quickly verifying identity, face recognition technology is often used in various security inspection equipment, such as installing a camera on the security inspection door, so that the security inspection door can quickly confirm the identity of tourists, without the need for security personnel to check ID cards, which is convenient The sec...

[0003] Because face recognition has the function of quickly verifying identity, face recognition technology is often used in various security inspection equipment, such as installing a camera on the security inspection door, so that the security inspection door can quickly confirm the identity of tourists, without the need for security personnel to check ID cards, which is convenient The security check improves the efficiency of security check at the same time, but because the security check gate is usually used in places with large traffic such as airports and bus passenger stations, the background image of the camera is complex during the shooting process, and there are usually other tourists’ face images in the background. The face recognition of the device causes interference. Not only that, but during the shooting process, the camera is relatively close to the face. According to the effect of the image captured by the camera, it is easy to distort the face and affect the judgment of the device, thereby reducing the existing The practicability of face recognition security gates
